What happens (in the dusty ag environment) when dust and chaff builds up on top and insulates the cooling fins? (out of sight, out of mind, most will never be checked or cleaned off, most likely).
I realize LED's don't make the kind of heat incandescent do, but the cooling fins are there for a reason.
On a related note, my late Uncle was a Master Electrician and wired MANY barns and other ag buildings from the coming of Rural Electrification up into the early 90's.
In barns and haymows they used fixtures with a "mason jar" globe to protect the bulbs and catch the hot pieces if one ever "popped".

It was surprising, over 30 or 40 years how much material could enter the box, winding up on to of the HOT porcelain lampholder.
Once in a while, you would hear of one lighting off and smoldering, NOT a good thing over hay and straw, probably caused a few barn fires when no one noticed in time.
